GAS-REGULATING BURNER.

SPECIFICATION forming part of Letters Patent No. 396,258, dated January15, 1889.

Application filed May 19, 1888. Serial No. 274,862. (No model.)

To all whom it may concern:

Be it known that I, HAROLD J. BELL, a citizen of the United States,residing at Gloucess ter, in the county of Camden and State of NewJersey, have invented new and useful Improvements in Gas-RegulatingBurners, of which the'following is a specification.

This invention relates to a simple and effect ive governing device forgas-burners,whereby the quantity of gas admitted to the burner can bereadily and accurately adjusted to the capacity of the burner and thepressure of gas automatically regulated without waste.

The invention consists in the construction and combination of parts, ashereinafter set forth and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is avertical section on the line y y of Fig. 2. Fig. 2 is a plan of the gasgovernor or regulator. Fig. 3 is a horizontal section on the line or 9;-of Fig. 1.

The numeral 1 designates a metallic shell provided at its lower end withinternal screwthreads. 2 for engaging a gas-fixture. This shell 1 isdivided about midway its length by a horizontal partition, 3, having acentral perforation, l, to afford a passage for gas into the upper partof said shell. The upper portion of the shell 1 is of somewhat largerdiameter than the lower part, and is provided at the top with ashoulder, 5, and internal screwthreads, (3, to engage an upperdetachable portion or cap, 7, which is externally threaded or otherwiseadapted to connect with a gasburner.

In the lower internally-threaded portion of the shell 1 is located anadjustable disk, 8, having perforations or gas-passages 9 and ascrew-threaded periphery, whereby it can be screwed into place by meansof any suitable instrument inserted into said perforations. This diskaffords a vertically-adjustable support for a float-valve, 10, whichconsists of a disk or float, 11, and a central tubular stem, 12, havingenlargements 13 and 14 at its opposite ends, thepurpose of which will behereinafter explained.

The cap 7 is formed with an inner chamber, 15, consisting of acontracted upper part closed at the top and extended below the attachingportion of said cap and an expanded lower part open at the bottom andapproaching the walls'of the upper part of the shell 1, within which itis inclosed. This chamber 15 affords a guideway for the float 11 andupper enlarged end, 13, of its tubular stem 12, as shown. Any leakage ofgas around the float 11 finds an exit through a tube, 16, that leadsfrom the expanded part of the chamber 15, as shown.

It will be seen by reference to Fig. 1 that the expanded part ofthechamber 15 does not extend to the partition 3, and that around saidchamber, between itand the shell 1, is an annular gas-passage, 17, whichcommunicates with separate vertical gas-passages 18, Figs. 1 and 3,which are cored in the wall of the contracted upper portion of thechamber 15, between it and the outer portion of the cap 7, of which itforms part.

As shown in Fig. 1, the upper portion of the cap '7 is internallyscrew-threaded to receive a disk, 19, the periphery of which is threadedto engage therein. This disk 19 is provided with a central perforation,20, forming a gaspassage, which is controlled by adjustable screws 21,that are located horizontally and end to end in said disk, as shown inFig. 2, to regulate the quantity of gas admitted to the burner. The disk19 is also provided 011 one side with a perforation for receiving theupper end of the tube 16, through which any accumulation of gas in theexpanded or enlarged portion of the chamber 15 is discharged into thespace above the disk 19, where the pressure is less than that below saiddisk. W hen the gas is turned off, the stem of the floatvalve 10 restson and is supported by the perforated disk 8, which can be adjusted toany required height. hen gas is admitted into the lower end of the shell1, it passes through 0 the perforations 9 and 4: into the upper part ofsaid shell, thence through the vertical passages 18 into the upper partof the cap 7, and through the passage 20 to the burner. The

normal pressure of gas against the under side 5 of the disk-float 11slightly raises said float and its hollow stem 12, so that a suflicientquantity of gas will pass through said stem into the upper contractedpart of the chamber 15 above the enlarged upper end, 13, of the I00float-stem, and there exert a counterbalancing pressure to prevent thefurther upward movement of the float-valve under ordinary gaspressure.Should the pressure of gas become excessive, however, it will so act onthe float 11 as to cause said float and its stem to ascend farther andbring the enlargement or shoulder 14 on the lower end of the stem intocloser proximity to the gas-passage 4, whereby said enlargement orshoulder 1-l is made to act as a valve to diminish the flow of gas, andconsequently reduce its pressure in the upper part of the device. If thegas-pressure in the lower part of the shell is decreased, the float andvalve will descend to permit a larger flow. The quantity of gas admittedto the burner is controlled by adjusting the screws 21 toward or fromeach other, so as to diminish or enlarge the gaspassage 20 to suit thecapacity of the burner employed. This can be done from the outside ofthe device without detachingany part or extinguishing the light.

The location of the adj Listing-screws 21 in the cap 7 for the purposeof adjusting the quantity of gas to the capacity of the burner and therelative arrangement of the lower gaspassage 4, float 11, and valve 14,as shown and described, result in the production of a volumetricgas-governing device, in which the pressure is automatically regulatedin an efficient and reliable manner.

lVhat I claim is 1. In a gas-governor or gas-regulating burner, thecombination, with a shell having a partition, 3, provided withgas-passage 4, and a cap, 7, having a central chamber, 15, and separatevertical gas-passages 18, of a float-valve, 1.0, comprising a disk, 11,and a tubular stem, 12, carrying a valve, 14, substantially asdescribed.

2. In a gas-governor or gas-regulating burner, the combination of theshell 1, having a partition, 3, provided with gas-passage 4, the cap 7,having chamber 15 and separate vertical gas-passages 18, the float-valve10, the perforated disk 19, and the tube 16, leading from the chamber 15and through the disk 19, substantially as described.

In a gas-governor or gas-regulatin g burner, the combination of theshell 1, having central gas-passage, 4, the disk 8, having perforations9, the cap '7, having chamber 15 and separate vertical gas-passages 18,the float-valve 10, the disk 19, having gas-passage EZO and screws 21,controlling said passage, and the tube 16, leading from the chamber 15and through said disk 19, substantially as described.

In testimony whereof I affix my signature in presence 05 two witnesses.
